The Densité 3 UHD-3901-UC is a dual-channel HD/3G to 4K UHD upconverter, which is designed to upconvert and process HD signals for 4K UHD broadcast production.
The UHD-3901-UC features broadcast quality upconverts with high-quality scaler, motion adaptive de-interlacer and color space conversion from ITU-R BT.709 to ITU-R BT.2020. Frame buffer is provided to keep 4K UHD outputs aligned with respect to a reference signal. The 4K UHD signals generated are output on quad link 3G SDI as per SMPTE ST-425-5 and supports two sample interleave (2SI) and square division quad split (SDQS) outputs, which are user selectable. The HD/3G embedded audio and metadata are delayed accordingly to keep synchronization with video before re-embedding in the first 3G link.
There are many benefits to adding the UHD-3901-UC to workflows, enhancing production capabilities. The UHD-3901-UC interfaces with Grass Valley HD cameras and K2 Dyno replay servers (at 6X) to create 4K UHD signals that can then be delivered to a 4K UHD production switcher in a very economical way, instead of using the switcher’s mix effects banks. The optional HDR processor, UHD-3901-OPT-HDR, allows conversion from SDR to HDR formats, supporting HLG (ITU-R BT.2100) and PQ (SMPTE ST 2084, ITU-R BT.2100) formats, with conversion between formats.
